Hi peste, thanks for your quick response. I have tried the link you sent but now the laptop is not turning on at all. Then I have seen that that ist for 14alc05 81yq and I have 15are05 81X2. Then I downloaded from this Poss #3 BIOS it works but my SN and MTM are showing INVALID in BIOS. How can I have my original SN and MTM number in BIOS. Please help. Thank you.

Hello good day brother.

I would like to ask for your assistance. I'm still encountering an issue with my Lenovo Flex 5-14ARE05 Laptop (Ideapad, Type 81X2, Serial: R90YSZF1, MTM: 81X2003HPHI). The problem began after I attempted to update the BIOS by double-clicking the EECN44WW.exe file downloaded from the Lenovo website. I also installed chipset drivers and other system drivers.

After the BIOS update, the laptop rebooted but now only shows a black screen. There is no POST, no display (not even on an external monitor), and the battery indicator does not show charging. The keyboard lights up, but I cannot access BIOS or use the Novo button. The device uses AMD architecture.

I tried flashing a fresh BIOS from Lenovo's official support site and also restored the DMI and Win key. Now, I am able to access the BIOS. However, when set to UEFI, the screen remains black with only backlighting. When switched to Legacy Boot, it gets stuck on the Lenovo logo. Secure Boot is already disabled. The system can detect the SSD and USB devices, and the Novo button works, but it won't boot from any bootable device—not even for OS installation or system recovery. I also attached my working BIOS version It's all working before I update also the current BIOS now with stuck black screen and stuck lenovo logo issue.

Thank you for the help..

Since you don't have the original bios, this one doesn't have DMI.

sorry to bother you again

what is the consequence if I flashed a bios without DMI?

if it is very important, I can try to get someone to dump a corrupted bios

thank you

Yes, it is very important, the DMI of a machine is to differentiate it from another machine.You just flash it and then add DMI later.
